Hello all,
I've a 4 year old climbing lace cap hydrangea and it has only just started to flower this year - but only grew two flower heads!
It's about 6 by 8 feet and is very healthy and leafy. I've read that they are encouraged to flower in more acidic soil. Ours is clay soil so I suspect quite alkaline.
I've also read that you can feed/ water the surrounding earth with something acidic to change the ph...
Trouble is I don't know what I should be using for this ? Anyone know of a soil acidifier ?!
Thanks!
